    Mounting the Control Link ACC The Control Link ACC is designed to be mounted in a case mullion, but may also be mounted in the raceway or in a metal electrical enclosure on the top of the case. Figure 3-1 shows examples of where the Control Link ACC may be mounted.

    Figure 4-1 - Ambient Temperature Calculation - additional heat sink For heater current greater than 10A, the heat sink of the Control Link ACC must be securely mounted against a large heat-conductive surface. Using thermal grease, the Control Link ACC has a metal back which acts as a heat sink, dissipating heat from the Triac that controls the heater.

  • Page 23: Step 4: Set The Network Baud Rate And Modbus Parity

    Figure 7-15 - NOTE: If you are networking Control Link ACC only for purposes of sharing a dewpoint sensor, you do not need to set a baud rate or parity. Set all dip switches or jumpers to the DOWN (OFF) position. This will allow the Control Link ACC to share a dewpoint sensor as long as the network is physically present and terminated correctly.

    Switch/jumper 7 determines the baud rate at which DEVICE the controllers communicate. When switch/jumper 7 AT END OF is ON, the Control Link ACC will operate at 9600 DAISY-CHAIN baud. If switch/jumper 7 is OFF (default), the Control Link ACC will operate at 19200 baud. Switch/jumper SHIELD 8 determines the MODBUS network parity.
